🐦 Do some birds have #PrettyPrivilege?
💫 New paper: doi.org/10.1098/rspb.2024.2846
We show that ~half the variation in research effort on 293 bird species in US+Canada is explained by just 3 factors: 1)visual appeal, 2)range size, & 3)# of universities w/in ranges. What we did & why it matters:🧵

We lost roughly $1 million in funding without warning. Projects cancelled included all of our bird monitoring work for the National Park Service & projects w/ the Bureau of Land Management on Gunnison's Sage-Grouse, Pinyon Jays & more. 1/4
Graphic with the following text followed by The Institute for Bird Populations logo: Emergency Appeal: Federal Funding Cut
Last week 9 of our federal grants were abruptly cancelled without cause.
If you can make a donation today, it will have a big impact.
Thank you for your support, The Institute for Bird Populations

💥BREAKING: Birds in a tropical pluvial rainforest of the Chocó have been quietly changing in morphology for 109 years. Some have shrunk, others grown. Tails grew longer, bills grew deeper. Even in forests with continuous cover, climate change may be rewriting evolution in real time.

hi everyone!! popping back into this space briefly to share the fundraiser for my long-awaited top surgery! eek! we are SO close to reaching my goal!

any form of interaction helps, even if you can't donate!
thank you, i love you, and keep taking care of each other! #transrights! gofund.me/60c167de1

🗺️ Why does this matter? Nonbreeding factors can limit population growth and manifest differently among populations and sexes across the annual cycle. For conservation of migratory animals, we need info about these complex patterns—we need to be studying female birds and multiple populations! 4/

⛰️ We also found that breeding popn’s occurring closer together don't necessarily overwinter closer together. Birds breeding @ Sevilleta NWR (NM) wintered mostly along the MX Baja Peninsula, whereas birds breeding only ~90km N of there @ Kirtland AFB (by Albuquerque) seem to winter in Sonora MX.. 3/
A multi panel figure. First panel top left shows nonbreeding dispersion probability density functions of male and female vireos that bred at Sevilleta (blue). Panel to the right shows Utah birds’ dispersion (orange), and the last panel shows Kirkland birds (yellow). Males are marked with squares, females with circles

💫 Unexpectedly, we found ♀ appeared to winter ~5° farther N than ♂—suggesting sexual segregation on the nonbreeding grounds, which may be explained by larger body size in ♀....the OPPOSITE trend expected among songbirds exhibiting sexual segregation (where ♂ typically winter farther north). 2/
A two panel boxplot. The left panel shows female and male nonbreeding longitude, where the females and males largely overlap. However, the left panel shows latitude, depicting clear separation with females occurring almost 5 degrees farther north than males. Boxes are in green, and there is an illustration of a vireo with a geolocator.

🐦 Never got around to posting about our paper on Gray Vireo #migration in @wilsonornithsoc.bsky.social (1 of my MS chapters), but better late than never!

We used light-level geolocators to track migration ecology of ♀ and ♂ Gray Vireos from 3 breeding sites in New Mexico and Utah USA… 👇 short🧵 1/

I feeeeellll this. I bought a sweet caddisfly case earring (look these up if you haven’t seen them!) with tiny black stones at TWS one year and the case fell off literally the first day I wore it 😭

Science is rarely a linear path from hypotheses to published papers. Here, I tell the story of our many ups and downs during the discovery of pollinator recognition. Hope you enjoy it! www.nature.com/articles/s41...

Today 14 scientific societies in #ecology #evolution and #marineScience are publishing the results of a survey that finds negative impacts of federal policies on food security, flood mitigation, infectious disease preparedness, and wildlife conservation: 🧪👩‍🔬 www.firsthandaccounts.org/impacts/2025...
This infographic describes the main results from a survey of members of 14 scientific societies. There is a pie chart showing that both academic (58%) and non-academic (42%) responded to the survey. It lists statistics: 85% of respondents reported uncertainty about the future; 71% reported federal training programs were "very" or "extremely important"; 83% reported negative impacts or irreparable harm on their field of science. There is a word cloud summarizing open-ended responses with the largest words "student research fund federal grant". Eight major themes in the responses are listed: disruption of research with societal important; concerns of closure of the USGS Bird Banding Lab; Early Career Bottleneck; Restricted Freedoms including travel and speech; Decline in Government Efficiency and Expertise; Concerns about Biased/Removed Data and Data Gaps; Concerns about the Ability to Meet Legal Mandates; and From Positive Impact to Irreparable Harm. There are icons for each participating society and a QR code for website and data availability.

ad to come, but I'm looking for an M.S. student to study the conservation genomics of swift foxes on the American Prairie Reserve in Montana beginning 9/1. this is a collaboration w/ Smithsonian & Justine Becker; strong candidates will have prior genomics experience and be up for remote fieldwork

🚨 NEW PAPER ALERT! 🚨

Led by Erin Morrison and @ajshultz622.bsky.social, we compiled the AvianLexiconAtlas to categorize all 10,906 bird species’ English common names. Here are some general trends we uncovered… journals.plos.org/plosone/arti... 1/4

Not sure if my cis pals are aware of this, but if your trans friends are sobbing in their office today this is one of the (many) reasons why:

If this spending bill passes the Senate and is signed into law in its current form, all but the most financially fortunate transgender people will be forcibly detransitioned regardless of their ability - or inability - to produce their own sex hormones.

This is a ten thousand-alarm fire.
